  • Receiving data on a networked computer in a reduced power state
    Patent number: 6985969
    Abstract: A networked computer includes a system controller having a network interface. When the networked computer enters a reduced-power state, the network interface receives frame data. The network interface filters the frame data and saves selected frame data to a memory. The memory provides the frame data to the system controller.
    Type: Grant

  • Transmitting data from a host computer in a reduced power state by an isolation block that disconnects the media access control layer from the physical layer
    Patent number: 6662234
    Abstract: A computer system controller monitors events. When a host processor enters a reduced-power state, the controller monitors network events, computer system events, and external events. The controller may respond to the events by transmitting frame data over the network. Before transmission, the frame data is stored in a memory.

  • Network interface for transmitting data from a networked computer in a reduced power state
    Patent number: 6459705
    Abstract: A network interface is provided for a host computer system that includes a host computer connected to an external computer network via an external network interface. The external network interface includes a host computer physical layer that provides a connection to the external computer network, a host computer media access control layer connected to the host computer through a media independent interface, and an isolation block connected to the media independent interface between the host computer physical layer and the host computer media access control layer. The isolation block is activated when the host computer enters a sleep state such that the host computer media access control layer is disconnected from the host computer physical layer and the network interface is activated. The network interface comprises a network interface media access control layer that is connected to the media independent interface.
